Abstract
We have used a CO2 laser as a heating source to fabricate a single-mode fiber couplers. The process consists of fusing and stretching two standard single model fibers initially maintained in lateral contact. We have fabricated 3 dB couplers at 1500 nm with insertion loss < 0.5dB. We also have fabricated multiplexers such as a 100% coupler at 1310 nm and at 1550 nm. The channel isolation of these components are > 30dB with a bandwidth of 30 nm at -30dB. Finally, a coupler with a long constant waist have been fabricated.
